My F 250 when I go to start it the glow plug light nand the engine light blinkes on and off, it will not go out so I can start it. When the lights go out it will start and runn for a few moments then the lights start flashing and it quits and now it will not go out, and it will not start. I have checked glow plugs and injectors wireing fuel and new fuel filter, and I have replaced the IDM?
